Frixa et al.showed that the miR-128-3p, which is up-regulated in lung cancer tissues, has [[Drosha]] and [[Dicer]], two key enzymes of MicroRNAs processing, as the main modulation targets leading to the widespread downregulation of MicroRNA expression. They observed that the MicroRNAs downregulation induced by miR-128-3p contributed to the tumorigenic properties of lung cancer cells. In particular miR-128-3p-mediated MicroRNAs dowregulation contributed to aberrant SNAIL and ZEB1 expression thereby promoting the epithelial-to-mesenchymal transition (EMT) program. Drosha also resulted to be implicated in the control of migratory phenotype as its expression counteracted miR-128-3p functional effects. The study provides mechanistic insights into the function of miR-128-3p as a key regulator of the malignant phenotype of lung cancer cells. This also enforces the remarkable impact of Drosha and Dicer alteration in cancer, and in particular it highlights a role for Drosha in NSCLC cells migration
